Method Detail

getOperator

public SqlCompare.Operator getOperator()

getSignature

public String getSignature()

Description copied from class: QueryModelNodeBase

Default implementation of QueryModelNode.getSignature() that prints the name of the node's class.

Specified by:

getSignature in interface QueryModelNode

Overrides:

getSignature in class QueryModelNodeBase

Returns:

The node's signature, e.g. SLICE (offset=10, limit=10).

visit

public <X extends Exception> void visit(RdbmsQueryModelVisitorBase<X> visitor)
           throws X extends Exception

Specified by:

visit in class RdbmsQueryModelNodeBase

Throws:

X extends Exception

hashCode

public int hashCode()

Overrides:

hashCode in class BinarySqlOperator

equals

public boolean equals(Object obj)

Description copied from interface: QueryModelNode

Returns true if this query model node and its children are recursively equal to o and its children.

Specified by:

equals in interface QueryModelNode

Overrides:

equals in class BinarySqlOperator
